Abstract
OBJECTIVE To evaluate fetal thoracoamniotic shunting for isolated large macrocystic congenital cystic adenomatoid malformations (CCAM) of the lung. METHODS This was a retrospective study of 11 fetuses with macrocystic CCAM who underwent thoracoamniotic shunting. This procedure was offered if fetal hydrops or signs of evolving hydrops (such as ascites or polyhydramnios) were present, or when there were very large lesions or lesions rapidly increasing in size. If there were multiple large cysts within the lesion, a single shunt was used, aiming to traverse several cysts. RESULTS Shunts were inserted at a mean gestational age of 24.6 (range, 17-32) weeks. Marked mediastinal shift was present in all cases. Six fetuses were hydropic and, of the remaining five, one had severe polyhydramnios, three had lesions that were rapidly increasing in size and one had a very large lesion at initial presentation. In total, four cases had polyhydramnios. Shunting one cyst always decompressed the entire lesion and hydrops and/or polyhydramnios resolved in all surviving fetuses. One hydropic fetus that underwent the procedure at 17 weeks died 1 day later. The shunt dislodged in one case and the lesion did not re-expand. No mother went into labor or had ruptured membranes before 35.6 weeks. Mean gestational age at delivery was 38.2 weeks (n = 10). All pregnancies were delivered vaginally, with no maternal complications. All newborns had uneventful lobectomies, and pathology confirmed CCAM in all cases. CONCLUSION Fetal thoracoamniotic shunting for large macrocystic CCAM is associated with favorable outcome in most cases, and should be considered in severe cases even before hydrops develops.

Abstract
Twin-twin transfusion syndrome (TTTS) is a condition unique to monochorionic pregnancies, although very few case reports described the syndrome in dichorionic placentas. The aetiology of TTTS relies in the presence of at least 1 arterio-venous placental anastomosis, through which unequal blood exchange from one twin (donor) to the co-twin (recipient) occurs. The diagnosis of TTTS relies on the sonographic detection of oligohydramnios in the donor's sac and polyhydramnios in the recipient's sac in the second trimester, although signs of TTTS are present since the first trimester. Treatment options for TTTS include serial amnioreduction, septostomy, selective feticide of the apparently sick twin, and selective photocoagulation of placental vessels (SLPCV). Because of the growing evidence that SLPCV is the most efficacious therapy compared to amnioreduction with/without septostomy, the authors reviewed in details the effects of SLPCV on fetal growth and circulation. The authors further explore literature with regard to the prognostic factors. Finally, because Quintero staging system is actually under debate, they discuss the most recent findings on this topic and propose a new staging system to assess severity of TTTS at presentation (Rossi staging system). New topics for future research, which would probably further clarify the natural history of TTTS, are also proposed.

Abstract
Multiple pregnancies represent 2% of all pregnancies but account for 20% of admissions to neonatal intensive care units. The outcome of multiple pregnancies is mainly dependent on chorionicity. Most perinatal complications are 3 to 12 times more prevalent in monochorionic pregnancies. The increased mortality and morbidity in this setting are mainly related to vascular anastomoses on the chorionic plate, joining the two fetal circulations. Intrauterine death of a monochorionic twin leads to exsanguination of the survivor, with fatal outcome in 20 to 30% of cases and a similar rate of severe ischemic complications. The most severe and acute complication is the twin-to-twin transfusion syndrome (TTTS). The main clinical manifestations of TTTS are the polyuric polyhydramnios--oliguric oligohydramnios sequence in the recipient and donor twin, respectively. TTTS is associated with a perinatal mortality rate of around 90%, and neurological sequelae are present in 20-40% of survivors born at around 25 weeks. Serial amnioreduction was long the only fetal therapy for TTTS, improving the survival rate to around 50% for at least one twin delivered at around 28 weeks, and reducing the risk of sequelae to around 20% among survivors. We have developed an intrauterine fetoscopic surgical treatment for TTTS. A 2-mm endoscope and a diode laser fiber are introduced percutaneously, under local anesthesia, through a single 3-mm trocard Coagulation of feto-fetal anastomoses on the chorionic plate leads to the survival of at least one twin in around 80% of cases at 33 weeks. Fewer than 10% of survivors have sequelae, mainly related to prematurity. We conducted a randomized controlled trial that confirmed the superiority of laser therapy over amnioreduction. The long-term outlook of these infants is good, with up to 6 years of follow-up.

Abstract
INTRODUCTION An acardiac fetus is the most severe malformation seen in humans. It is an extremely rare complication, occurring in approximately 1% of all monozygotic twin gestations, with an incidence of about 1 in 35,000 births. This malformation happens as a result of the syndrome of reversed arterial perfusion of the acardiac twin from the other normal fetus (pump twin), due to the presence of arterio-arterial anastomoses in a monochorionic placenta. Several obstetric and perinatal complications have been associated to this anomaly and several treatments have been proposed to reduce the morbimortality of the pump twin. There's no report in MEDLINE about the treatment of twin gestations with acardiac fetus through septostomy. CASE REPORT The present article reports a case of reversed arterial perfusion sequence complicated by polyhydramnios diagnosed at 19th week of pregnancy, treated with septostomy and serial amniodrainage. DISCUSSION This case presented it demonstrate favorable development of the gestation, with labor happening at 35 weeks gestation and pump twin presenting good vitality conditions. In cases with no major factors of bad prognosis, septostomy combined with amniodrainage could be an interesting therapeutic option for a safe and efficacious management of selected cases of TRAP sequence.

Abstract
Bronchopulmonary sequestration (BPS), a non-functional pulmonary tissue mass, when complicated by fetal hydrops, carries a high risk of perinatal mortality. However, a limited number of cases of BPS complicated by fetal hydrops with an informative clinical course have been reported. We report here on three cases of BPS complicated by fetal hydrothorax and hydrops that were successfully treated by pleuroamniotic shunting, which should be considered as a treatment option for fetal hydrothorax and hydrops associated with BPS.

Abstract
OBJECTIVES To investigate maternal hemodynamic changes following laser therapy and amnioreduction in twin-to-twin transfusion syndrome (TTTS). METHODS Thirty-nine cases with severe TTTS were treated at 16-26 weeks of gestation. Maternal hemodynamic evaluation was performed, including heart rate (HR), arterial pressure and echocardiography with calculation of shortening fraction (SF), left atrial dimensions, stroke volume (SV), cardiac output (CO) and total vascular resistance (TVR), before and 6 h and 24 h after placental surgery. Hemoglobin (Hb), hematocrit (Ht) and protein levels were also measured. Cases were retrospectively divided into groups according to treatment: Group A had laser therapy followed by amnioreduction >1000 mL (n = 25); Group B had laser therapy followed by amnioreduction <1000 mL (n = 14). RESULTS The mean gestational age at inclusion was 21 (range, 16-26) weeks. The mean amniotic fluid withdrawal was 1700 (range, 1000-3000) and 300 (range, 150-800) mL in Groups A and B, respectively. Cases in Group A showed a decrease in mean arterial blood pressure (P = 0.011) and in TVR (P < 0.0001) and an increase in CO (P = 0.008) and SV (P = 0.022). There was no difference in HR. Significant hemodilution developed as early as 6 h after the procedure, with a reduction in Ht (P < 0.0001), plasma protein (P < 0.0001) and Hb levels of 1.2 g/dL on average (P < 0.0001). There were no changes in any parameters in Group B. CONCLUSIONS Amnioreduction of severe polyhydramnios in TTTS induces maternal hemodynamic changes within the first 6 h that persist at least 24 h after treatment. These adaptative changes are compatible with hemodilution.

Abstract
The twin-twin transfusion syndrome (TTTS) complicates approximately 15% of monochorionic twin pregnancies. Severe TTTS is associated with poor neonatal outcome and a relatively high rate of neurological abnormalities. Some studies have suggested this outcome to be more severe in cases treated by amnioreduction. In this paper we present a hypothesis that radical amnioreduction performed after 24 weeks of gestation might cause a shift of blood from the fetus into the placenta. This could explain some of the severe neurological outcomes, such as hypoxic ischemic brain damage, seen in these cases.

Abstract
Without intervention, the development of hydrops fetalis secondary to cystic adenomatoid malformation of the lung (CAML) implies a 100% mortality rate. Conversely, four CAML cases with in-utero resolution of hydrops fetalis after prenatal betamethasone therapy with good clinical outcome have been reported in the literature. The mechanism is speculated to be the effect of corticosteroid in improving lung maturation. Here we present another CAML case with resolution of hydrops fetalis after prenatal betamethasone therapy but which was followed by later intrauterine death. We speculate that the resolution of the CAML lesion itself may be more important in determining the clinical outcome than the resolution of hydrops. The association between prenatal betamethasone therapy and resolution of hydrops may be related to a different mechanism other than improvement of lung maturation.

A 33-year-old woman presented at 31 weeks' gestation with polyhydramnios that required repeated amniodrainage. An antenatal scan at 32 weeks showed dilated fetal bowel loops, which were not confirmed on subsequent scans. The amniotic fluid karyotype confirmed 47,XXX. After birth, jejunal obstruction was confirmed. To our knowledge, this is the first report of an association of triple-X syndrome and jejunal atresia.

Abstract
OBJECTIVES To determine whether the vascular anatomy of monochorial placenta influences the success of amniotic septostomy for the treatment of chronic mid-trimester twin-twin transfusion syndrome, we report placental anastomoses and perinatal data of 13 pregnancies treated by amniotic septostomy in combination with amnioreduction (AR). The placental anastomoses were delineated postnatally by perfusion studies. Perinatal outcome was also evaluated in relation to umbilical artery Doppler waveform of the donor twin. RESULTS The median gestational age at septostomy was 21 weeks (range 18 to 25.5 weeks). Amniotic septostomy in combination with single AR procedure successfully resolved polyhydramnios in all cases. The median gestational age at delivery and the septostomy to delivery interval were 27 weeks (range 20 to 34 weeks) and 4 weeks (range 0.3 to 13.6 weeks), respectively. Of the 26 fetuses, 10 died in utero and four died within a week of life, with a combined survival rate of 46%. There was no relation between the clinical outcome and angioarchitecture of the placenta. However, pregnancy loss was higher in the donor twin with absent end-diastolic flow umbilical artery Doppler waveform than those with end-diastolic flow (85 vs 17%; p < 0.001). CONCLUSION This study suggests that although amniotic septostomy is a promising method for the correction of oligohydramnios and/or polyhydramnios, perinatal survival rate does not depend on angioarchitecture of the placenta. Instead, umbilical artery Doppler waveform of the donor twin may be a better marker for survival rate.

Abstract
OBJECTIVES To assess the relationship between the volume of amniotic fluid removed and the change in amniotic fluid index (AFI) and calculate an equation describing this association. MATERIALS AND METHODS A retrospective analysis of 19 amnioreduction procedures performed in our unit. Multiple regression analysis was used to assess the effect of gestational age and pre-procedure AFI on the change in AFI (DeltaAFI) after adjusting for the volume removed. RESULTS As expected, a significant linear relationship was found between the change in AFI and the volume removed (r = 0.82, n = 19, p < 0.0001). DeltaAFI was not dependent on the gestational age or the pre-procedure AFI. The equation describing the association between the volume removed and DeltaAFI was: volume = (DeltaAFI - 2. 26)/0.008, which is close to 1 cm DeltaAFI for every 100 ml removed. DISCUSSION Using the described equation, it is possible to predict the required volume to be removed in order to achieve a particular DeltaAFI, which may reduce the need to interrupt the procedure to measure the AFI. However, the limitation of AFI as a semiquantitative assessment of the liquor volume, together with its inter- and intra-observer variations mean this equation should be used only as a guide.

Abstract
We report on a patient with an eight-year history on maintenance hemodialysis treatment without residual renal function in whom pregnancy was successfully managed through to the 29th week. During this time, under carefully modified dialysis treatment, the nephrologic course, as well as materno-fetal flow relationships were unremarkable. Fetal development was appropriate for gestational age. However, pregnancy was complicated by polyhydramnios, which necessitated i.v. tocolysis. In the 28 + 6th week of gestation, cesarean section was performed because of an antibiotic-resistant fever of unclear origin which ceased within two days of delivery. Although the postnatal course of the adequately developed baby was complicated by the respiratory distress syndrome, normal development continued. We emphasize that the intensive interdisciplinary cooperation of nephrologists and obstetricians is imperative for the successful management of pregnancy under these conditions. In these pregnancies, the main fetal problems consist of premature labor because of polyhydramnios, preterm delivery, intrauterine growth retardation and stillbirth. The mother is threatened by the development of superimposed pre-eclampsia, left ventricular failure because of volume overload and progressive anemia. In order to maintain a well-balanced homeostasis, intensification of dialysis therapy by an increase in frequency and duration is the most important therapeutic approach. Accurate fetal monitoring including frequent examination of the feto-maternal circulation by Doppler sonography as well as attentive surveillance of the mother is required to recognize the above mentioned complications.

Abstract
OBJECTIVE To measure acute and chronic changes in the placenta and amniotic fluid associated with performance of decompression amniocentesis in pregnancies with the twin oligohydramnios-polyhydramnios sequence (TOPS). METHODS Amniotic fluid pressures, placental thickness, placental perfusion, and amniotic fluid volumes were measured in each sac of a monochorionic diamniotic twin gestation before and after decompression amniocentesis. Indigo carmine was injected into the polyhydramnic sac after decompression, and fluid from the oligohydramnic sac was sampled after equilibration. Spectrophotometric analysis of amniotic fluid specimens was performed for dye detection. Amniotic fluid volume and placental perfusion studies were repeated 1 week later. RESULTS Three patients with TOPS were enrolled, and decompression amniocentesis was performed in the midtrimester. After decompression, amniotic fluid volume decreased in the polyhydramnic sac, amniotic fluid pressures decreased in both sacs, placental thickness increased, and umbilical artery Doppler velocimetry was unaffected. The amniotic fluid volume increased acutely in only one oligohydramnic sac after decompression, and ultrasonographic examination, amniotic fluid spectrophotometric analysis, and placental pathologic examination all identified interfetal membrane disruption as the etiology. CONCLUSIONS Decompression amniocentesis as a treatment for TOPS does not result in acute or chronic changes in the amniotic fluid volume of the oligohydramnic sac in the absence of interfetal membrane disruption.

Abstract
OBJECTIVE To report our experience with intentional puncture of the intervening membrane ('septostomy') for the treatment of the twin oligohydramnios-polyhydramnios sequence (TOPS). METHODS 12 patients were diagnosed with TOPS based on ultrasonographic findings. A 20- to 22-gauge spinal needle was used to puncture the membrane between the twins without any attempt at amnioreduction in 9 patients, while the procedure was combined with amnioreductions in 3 patients. RESULTS Gestational age was 23.1 +/- 3.3 weeks at the time of septostomy and 31.1 +/- 4.4 weeks at delivery. Rapid accumulation of fluid around the 'stuck' fetus occurred in all cases following a single procedure. Three of the 24 fetuses died in utero and 1 died on the fifth day of life, for a combined survival of 83.3%. In the survivors, the septostomy to delivery interval ranged between 0.6 and 13 weeks (mean +/- SD 8.3 +/- 4.8). CONCLUSION Amniotic septostomy is a promising new method for the management of TOPS and is associated with survival rates that are better than, or comparable to, more invasive modalities. A multicenter trial comparing septostomy to other modalities is warranted.

Abstract
We present an unusual case of TRAP sequence (twin reversed arterial perfusion) with persistent polyhydramnios despite spontaneous thrombosis of the vena umbilicalis of the acardius. Serial amnioreduction was performed owing to considerable maternal discomfort and preterm labor. After three procedures, spontaneous abortion occurred. Unexpectedly, the normal twin had an apparently recent constriction of the right forearm. We hypothesize that limb constriction could be a rare but specific complication of aggressive amnioreduction.

Abstract
The objective of this study was to determine the effects of removal of amniotic fluid in cases of symptomatic severe polyhydramnios on Doppler waveform indices of the uterine and umbilical arteries and flow velocities of the uterine arteries. Nine women underwent therapeutic amniocentesis during ten pregnancies for symptomatic polyhydramnios due to Beckwith-Wiedemann Syndrome (n = 1), esophageal atresia (n = 2), chorioangioma (n = 1), twin-twin transfusion syndrome (n = 3), a presumed autosomal recessive syndrome (n = 2), and an unbalanced double translocation (n = 1; partial dup 3q and partial del 9p syndrome). An average of 2.78 +/- 0.9 (range 1-4) 1 of fluid were removed at each procedure between the gestational ages of 18 and 34 weeks (mean of 28 weeks). The systolic/diastolic (S/D) ratio, pulsitility index (PI), and resistance index (RI) of the uterine and umbilical arteries were obtained before and after the procedure using color and pulsed Doppler. After angle correction, the peak systolic velocity (PSV) and mean velocity (MV) in centimeters/second (cm/s) of the uterine arteries were also determined. The presence or absence of a uterine artery waveform notch was determined. Dominant uterine arteries were defined as those with lower impedance indices or higher flow velocities. Statistical analysis was performed with the Wilcoxon signed-rank test. Significance was set at P < 0.05. There was a significant increase in the median value of the uterine artery MV (43.8 vs. 81.1 cm/s, P = 0.005) and PSV (74.2 vs. 125.5 cm/s, P = 0.007) after amniocentesis. The uterine S/D (3.0 vs. 1.84, P = 0.007), PI (1.12 vs. 0.68, P = 0.008), and RI (0.60 vs. 0.45, P = 0.005) impedance indices significantly decreased following amniocentesis. When uterine arteries were categorized as dominant vs. nondominant, there were greater improvements in impedance indices and flow velocities in the nondominant uterine arteries. There were three cases of unilateral and one case of bilateral early diastolic notches of the uterine artery waveforms which either resolved (n = 4) or improved (n = 1). There was no effect on the umbilical artery impedance indices. Therapeutic amniocentesis significantly improved uterine artery impedance indices and resulted in improved flow velocities, while there was no effect on umbilical artery waveform indices. The procedure resulted in the disappearance or improvement of the uterine waveform notch. Our findings suggest that in cases of severe polyhydramnios abnormal uterine artery velocimetry may not be due to lack of trophoblastic invasion of the spiral arteries but to increased intrauterine pressure secondary to polyhydramnios.

Abstract
This study evaluates the role of color Doppler ultrasonography in the identification of the communicating placental vessels in pregnancies with twin-twin transfusion syndrome and acardiac twins. In 18 pregnancies with twin-twin transfusion syndrome and two with an acardiac twin, color Doppler studies of the placental vasculature were performed before fetoscopy for laser coagulation of the communicating vessels. In six cases of twin-twin transfusion syndrome the placental attachment of the intertwin membrane could be visualized. Pulsatile arterial blood flow was observed from the donor to the recipient twin that disappeared after laser therapy. In both cases of acardiac twins, one communicating vessel with pulsatile and another vessel with nonpulsatile blood flow in the opposite direction could be identified. Color Doppler imaging is unlikely to play a major role in assisting endoscopic laser separation of chorioangiopagus in patients with acute polyhydramnios, but it may prove to be useful in the early identification of pregnancies at risk of developing twin-twin transfusion syndrome.

Abstract
Congenital obstructive uropathy is a relatively common developmental malformation, and severely affected fetuses die soon after birth from oligohydramnios-induced pulmonary hypoplasia or renal failure. Prenatal ultrasonography can reliably diagnose the specific anatomic defect, and using fetal urine sampling we can determine the extent of renal damage in utero with reasonable certainty. With these diagnostic tools and an understanding of the natural history of congenital obstructive uropathy we can now make rational decisions regarding treatment. Clinical experience has demonstrated that the selected fetus may benefit from in utero decompression, either by percutaneous shunt placement or open fetal surgery. However, each of these procedures has certain risks that must be carefully weighed against the expected benefits. Future techniques using fetoscopic surgery may provide the ideal therapeutic approach.

Abstract
Bilateral pleuroamniotic shunting was performed at 33 weeks' gestation in a fetus with bilateral hydrothorax, hydrops, and gross polyhydramnios. The procedure was successful, but acute amniotic fluid leakage into the maternal peritoneal cavity occurred soon after. This produced marked maternal discomfort and transient oligohydramnios, with consequent fetal distress. Expectant management was adopted in view of fetal lung immaturity. Resolution of maternal ascites occurred within 24 hours and the fetal heart rate normalized as amniotic fluid reaccumulated. The pregnancy progressed uneventfully thereafter.

Abstract
Congenital chylothorax is an uncommon but well-described condition. Recurrent congenital chylothorax is extremely rare. Yancy and Spock (1967) reviewed 31 reported cases of spontaneous chylothorax which occurred in the first 2 months of life and noted that male infants were affected twice as commonly as females. Two other cases of recurrent congenital chylothorax in male offspring (Defoort and Thiery, 1978; Reece et al., 1987) led to the suggestion of possible X-linked recessive inheritance. We describe a case of recurrent congenital chylothorax in which two consecutive female infants in a sibship were affected. The underlying cause of this disorder remains unknown. Inheritance as an X-linked recessive is not possible and this case is suggestive of autosomal recessive inheritance. The case also serves to emphasize the need for caution in counselling for recurrence risks when the underlying aetiology of the disorder is unknown.

Abstract
Two cases of acute polyhydramnios complicating twin pregnancies were treated with repeated amniocentesis for the relief of extreme abdominal discomfort and to prevent imminent premature labor. The procedure was found to be safe and resulted in prolonging the pregnancies by 14 to 11 days respectively. This management, with the addition of tocolysis and close fetal surveillance (which resulted in 2/4 living children) can offer some hope in an otherwise hopeless situation.
